Ranshima Station opened on 12 December 1902 when the private Hokkaido Railway established a track between it and Shikaribetsu. By 28 June 1903, the track had been extended north from here to Otaru Chūō (now Otaru). By 19 Oct 1904, link ups to the track south of Shikaribetsu had allowed through traffic all the way to Hakodate. After the Hokkaido Railway was nationalized on 1 July 1907, Japanese Government Railways (JGR) took over control of the station. On 12 October 1909 the station became part of the Hakodate Main Line. On 1 April 1987, with the privatization of Japanese National Railways (JNR), the successor of JGR, the station came under the control of JR Hokkaido. From 1 October 2007, station numbering was introduced on JR Hokkaido lines, with Ranshima Station becoming "S17".
